| Abstract: | The deactivated V-P/H-ZSM-5 zeolite catalyst was refreshed by distilled water,and its catalytic activity after refreshing was investigated through changing the temperature,velocity or disposed time of distilled water .The catalyst was characteristized with SEM,FTIR,XRD.The experimental results show that,the best refreshed catalyst is obtained with distilled water flow rate of 0.3 mL·min~(-1),and refreshing for 3 h at 400 ℃. |
